  • 3. The Body Systems Work Together The heart is like the president of the organization.  Some of the bodys systems are directly connected to the heart, while others are not.  Even if the heart is not directly involved in the system, it still plays a part.  If the heart isnt working, nothing else is working either.  The heart actively participates in the circulatory system, while it just keeps an eye on the respiratory and excretory systems.
  • 4. The Body Systems•The Digestive System•The Skeletal System•The Circulatory System•The Muscular System•The Nervous System•The Respiratory System
  • 5. The Digestive System By Rowan
  • 6. Where Your Food Goes When you eat your food, do you know where it goes? It goes into your digestive system. Your digestive system is made up of your mouth, pharynx, esophagus, liver, stomach, small intestines, large intestines, appendix, rectum, and anus! That is a lot of parts!
  • 7. Care For Your Digestive System!  Chew your food well and swallow slowly!  Drink plenty of water to help move food through your digestive system!
  • 8. Facts About Your Digestive System It takes 2 to 3 weeks to digest gum. Juices in the stomach break down the proteins. Food stays in your stomach for 2 to 3 hours. Food goes down your esophagus and into your stomach where juices break down the proteins. Then it goes down your small intestine to the large intestine and gets removed by the digestive system.
  • 9. Get the Picture?
  • 10. The Skeletal SystemBy Alex
  • 11. The Skeletal SystemThe skeletal system isthe system thatsupports us and givesus our shape.
  • 12. Main Structures of the Skeletal System•Two main structures form theskeletal system: cartilage andbone. Cartilage is largely composed of water and contains no nerves or blood vessels. Bones are hard on the outside. Inside they are soft, but strong. Red and white blood cells are made inside the bones.
  • 13. The Circulatory System By Nathaniel
  • 14. The Circulatory SystemThe circulatory system performs many vitalfunctions. Your heart pumps blood andnutrients to tissues all over the body. Thecirculatory system is also important in theremoval of wastes and in several other bodyprocesses.
  • 15. The Main Organ of the Circulatory System The main organ of the Circulatory system is the heart.  The hearts primary function is to pump blood to all parts of the body, bringing nutrients and oxygen to the tissues and removing waste products.
  • 16. The Muscular System By KelliThe Muscular System is made up of 630 muscles.
  • 17. The Muscular System Helps Your Body MoveMost muscles worktogether in pairs. Onemuscle pulls while the othermuscle relaxes. When youbend your arm the bicepsmuscle pulls and thetriceps muscle relaxes.When you make your armstraight, the biceps musclerelaxes and the tricepsmuscle pulls.
  • 18. The Function of MusclesMuscles are very important. They help you doalmost everything — from pumping bloodthroughout your body to lifting your heavybackpack. You control some of your musclesand others, like your heart, do their jobs withoutyou thinking about them at all.
  • 19. Interesting Facts About Muscles Muscles are bundles of cells and fibers. Muscles work in a very simple way. All they do is tighten up--that is, contract--and relax. You have two sets of muscles attached to many of your bones which allow them to move. There are 630 active muscles in your body and they act in groups. Muscles can only pull. They never push.
  • 20. Did you know? You use 17 muscles when you smile. You use 43 muscles when you frown.
  • 21. Nervous Systemby Jesse The main parts of the Nervous System are the Brain, the Nerves, and the Spinal Cord.
  • 22. The Brain The brain is much more complex than the spinal cord. It has many divisions within it.  The brain stem controls most of the life systems commands such as breathing and heartbeat.  The cerebellum controls balance and the coordination of muscles to move.  The cerebral cortex is the most advanced part of the brain. This is where conscious thought takes place.
  • 23. The Spinal Cord The spinal cord is a long bundle of white nerve matter that is found in the middle of the spinal column. It is a link between the brain and the body.
  • 24. Respiratory System By Paige
  • 25. Function of the Respiratory SystemThe primary function of the respiratory systemis to supply the blood with oxygen in order forthe blood to deliver oxygen to all parts of thebody. The respiratory system does this throughbreathing. When we breathe, we inhale oxygenand exhale carbon dioxide. This exchange ofgases is how the respiratory system getsoxygen to the blood.
  • 26. The Respiratory SystemAir is breathed in throughthe nasal cavity and/ormouth and down throughthe throat (the pharynx).The air passes down thetrachea (the windpipe),through the left and rightbronchi, and into thelungs. Oxygen in theblood is delivered to bodycells.
